Description

720710 – PUMP ASSEM, SOLUTION SPRAY, NC20/NC30/NC40 – Works with all Harshaw, Engelhard, Atotech USA, Atlas and Auto Technology Company fog and cyclic corrosion test chambers. PURPOSE: The purpose of the solution spray pump is to move solution from the solution reservoir to the spray bar header assembly and pressurize it for spraying. LOCATION: The solution spray pump is located on the component plate in the back left corner of the control cabinet area. It is found by removing the front access panel on the control cabinet. It is behind the water trap, mounted on a plastic plate that is fastened to the component shelf. FUNCTION: This 220VAC magnetic drive solution pump is wired to output # Y11 (CR4) for the computer controls, and Y4 (CR3) for the standard controls. This pump is only turned on when the solution spray option has been programmed into a test cycle. When a test step requiring solution spray is specified, the appropriate contactor relay (CR4 for computer controls and CR3 for standard controls) is activated. This relay then sends voltage to the pump to turn it ON. The pump remains ON until the time has expired for that specific step in the cycle.
